A fuse state detection circuit is comprised of a first fuse element, a
second fuse element, and an output for carrying an output signal, the
output signal represents a first logic state when the first fuse element
is blown and the second fuse element is unblown and the output signal
represents a second logic state when the first element is unblown and the
second element is blown. The fuse state detection circuit produces an
output signal whose state is recoverable from a negative triggering event
and is capable of resolving itself to the correct state without the need
for a reset pulse. Methods of using the fuse state detection circuit,
such as a method of using fuse elements to control a setting within an
electronic circuit, the improvement comprising using a pair of fuse
elements to control a single setting, are also given.
